Powder Water Absorption Tester

The powder water absorption tester calculates the water absorption rate by measuring the change in mass of the sample before and after water absorption. It is used to determine the water absorption properties of materials such as powders and granules under specific conditions, providing reference data on the hygroscopicity of raw materials for industries such as coatings and plastics.
Selection
Focus on testing accuracy and ensuring that the sample capacity matches the daily sample volume. Check whether it complies with industry-standard testing methods. Consider the ease of instrument operation and data recording capabilities. Compare the testing speeds of different models to see if they meet the frequency requirements for testing.
